have invented certain now and useful Ian-- provements in Thinnecl Paint and-Processes of Drinking- Paint-'lh'inner; and we do declare the following to he a full,;clear, and exact description of the invention, such as will e.n

ahle others skilled in the art to which'it ap pertains to maln and use the same.

The, present invention relates to the treatment of oils partieula'rly petroleum distillates consisting: wholly or largely of paraffin hydroearhons. sueh as ordinary kerosene. for us as a thinner or turpentine substitute. in mixed paints,

The proress employed consists essentially in adding:- aleohol. for example grain alcohol, denatured alrohol or wood. alcohol. to the kerosene or similar oil. the amount of the al- ('ohol being equal to about 5 to 1091 by volume. relative. to th amount of the oil; the mixture is then heated to the boiling point, and the boiling is eontinued. for a period of ahout half hour. The. time of hoilingl is not ahsolutely fixed, hut may he varied more or less. depending upon the proportions of the ingredients. the gravity and other properties qt the oil and other eondi 'ions. rial which is vaporized during, tho boiling ogeration may ho led to a eondenser (oil and rerovered it desired.

The oil thus treated is used as a thinner in paints, for example by adding th'e same to a mixed paint ronsisi in; of linseed oil or vegetable. oil treated in acrordanee. with the proress of our ropendingappliration Serial No. 161,525. filed April l'J. M17. The tur pentino substitute prepared as above der-rribed may also} i added to paint oils generally as a thinner. l'or suh emlent use in the same. manner as mixtures of linseed oil and turpentine are omployed. The mixtures oi 1he, 0il as ahove treated, with ordinary dryingr oilsfor. the drying: oils produced in aeeordam o with our oopemling application above described. or the oil proc luced in areordani-e with the' process of Serial No. 130,038, tiled November 7., 1916. are. found to (try more quickly than without. ll addition of the turpentine suhslitutc produced in accordance with the present proeess.
